Social Capital and Contributions in a Public-Goods Experiment
通过公共品实验，检验社会资本（如信任和参与度）与个人贡献之间的关系，回应了调查测量方法有效性的争议。
Empirical studies from across the social and behavioral sciences find that social capital is associated with various measures of well-being, including economic growth and mortality. however, such evidence is plagued by concerns that survey-based measures of trust and participation are not meaningful; in particular, recent experimental evidence from trust games conducted by Edward L. Glaeser et al. (2000) calls into question the efficacy of the most prevalent measures of social capital employed in the literature.
